This paper shows that Investor-State Dispute Settlements (ISDS) makes multinational firms more aggressive by increasing cost-reducing investments with the aim to enlarge the potential compensation an ISDS provision may offer. While a larger investment reduces the market distortion, it will also...

Investor-state dispute settlements (ISDS) were supposed to become an integral part of multilateral trade and investment agreements although the partner countries of these deals do not suffer from substantial institutional weakness. This paper shows why multinational firms lobby for ISDS also in...
